Abstract
A low frequency exponential bass horn enclosure employing a large area unitary throat pathway, bifurcated at a substantially parabolic rearward channel wall, convertible to a front-loaded or rear-loaded configuration by the use of interchangeable parts, with driver access from the front. Intended for corner placement, however, fully enclosed horn channel allows for floor use. The axially-centered throat expands vertically, exhausts rearward, and is bifurcated at the back of the enclosure with two hard reflection points, comprising a single fold, in which the vertically arranged horn terminus exhausts with a forward-canted splay angle around a partially rectangular back chamber.
